Growonix Electric Shut Off Kit - Float Switch and Solenoid Valve

Automatic Tank Refill Control for Water Filters - 7.5 x 13 x 3.5 in

An unattended storage tank can overflow, and a filter that runs without a shutoff wastes water. This kit pairs a float switch with a solenoid valve to shut off feed water ahead of your water filter and to control on/off cycling of a booster pump. The float switch reads the tank level, and the valve responds.

Sold as a single kit, it suits hydroponic growers who run a water filter into a water or nutrient storage tank and want refilling to run on its own, whether in a home setup or a larger indoor operation.

Key Features & Benefits

• Float switch — mounts in your water or nutrient storage tank and tracks the level.
• Solenoid valve — installs at the front end of the water filter to shut off feed water.
• Booster pump control — manages on/off cycling of a booster pump if you have one installed.
• Automatic refill — when the tank drops to the set level, the system begins refilling the tank.

Who Should Use Growonix Electric Shut Off Kit

Use it if you run a water filter with a storage tank for hydroponic systems and want automatic level-based control. It is especially useful with a high pressure booster pump.

Frequently Asked Questions

Q: What comes in the kit?
A: The kit includes a float switch and a solenoid valve. You mount the float switch in the tank and install the valve at the filter inlet.

Q: Where does the solenoid valve go?
A: Install it on the front end of your water filter. From there it shuts off feed water before it reaches the filter.

Q: Where does the float switch go?
A: Mount it in your water tank or nutrient storage tank. It senses the level so the system knows when to refill.

Q: What happens when the tank level drops?
A: At the desired level, the float switch opens the solenoid valve. The booster pump, if installed, powers on and the system refills the tank.

Q: Do I need a booster pump?
A: No. The kit controls a booster pump if you have one, but the shutoff function works ahead of the filter either way.

Q: What is a solenoid valve?
A: It is an electrically operated valve that opens or closes water flow when it receives a signal. Here the float switch provides that signal.
